A missing herd has one concerned bison farmer in Cobleskill searching by ATV, by foot, and any means necessary to locate the group.

"I may have to rent a plane and do some of it from the air,” said Bison Island Farm Owner Brian Grubb.

More than 70 of the bison have been on the move since last week after breaking through a fence located on Grubb's second farm nearby.

They can graze for up to 11 hours a day and trail of up turned soil wherever they go, so keeping them off others' properties is also a concern.

Grubb says the buffalo stay together in herds and generally don’t bother the public, causing them to split and make search efforts difficult.

“If we can get the harassment to stop, they will come together and gather as a herd again,” Grubb said.

A recent Yellowstone National Park incident involving a young girl being tossed into the air by a bison is even more reason Grubb says not to approach the cattle, but instead call authorities.

“They’re not aggressive, but you don’t want to corner one because they are defensive,” Grubb said.

He’s currently working with the DEP and Richfield Springs Police to corral the 45 baby calves and 30 adult bison home.

“I think everyone wants to see these animals returned home safely. We will be as patient and as diligent as it takes to make sure that happens,” said Grubb.

If you spot any of the buffalo, police ask that you call them immediately at (518) 588-1402.
